To vif/ZZ whom tmay concern:

Be it known that LHARRYM. Pnfrrir, la

i citizen of the United States, and a resident of the city of New York, borough. of Manhat tan, in the county and State of New Yorlr. have invented a new and improved Theatrical Device, of which the foilowing is a full, clear, vand exact description. f

My invention relates to stage apparatus for theaters and amusement places of various kinds for producing illusory eects, and in particular for giving to passengers in an automobile or other vehiclev the eiect of iiying through the air from a height across a chasm.

in carrying out my invention. i provide an autoinohiie or other vehicle with wings and with means for spreading vibrating the wings to givethe desiredeffect, and also l rovide means for propelling the automoV hi e along a way or track and for supporting it when removed from the way or track, so that it may give an appearance of leaping from a clii to a trech located on the opposite side of the chasm and at a lower level. Fur thermorejA provide safety devices for insur ing the performance of this act in perfectly safe manner without any danger to the occupants of the vehicle.

The invention comprises other features, which will appear in the course of the suien joined description.

. respectively, of Fig. 2.

Reference is -to he had to the accompany ing drawings, forming a part of this specifican tion, in which similar chanrcteren ofreference indicate corresponding parts in all the figa ures.

Figure l is a bottom pian view of an automobile constructed in accordance with the principle of my invention.l Fig. 2 is a secu tional viewv ofthe same on the line 2 2 of Fig. l. Fig. 3 is a horizontal sectionai view on the line 3 3 of Fig. 2. Figs. L and 5 are ver tical sectional views on the lines i i and 5 5, Fig. 6 is a perspec tive view of a portion of the mechanism for operating the wings.` Fig. 7 is a sectional view of a portion of a stage, showing one manner of .controlling the operation'of the vehicle and 'illustrating thel scenery and course of fright of theauto'mobile. Figs. 8

and 9 are sectional views, on an enlarged.

scale, on the lines e 8 and 9 9, respectively, of Fig. 7. Fig. l0 is a plan of the track upon which the vehicle lands, showing a safety device for guiding the wheels; and Fig. i1 is a view similar tion.

Referring Jiirst to Figs. 7', 8, and @Sit will be ohserved that an automobile 11 is designed to run along the ton of a cliff l2 Yand when to Fig. 8, showing amodicanear the outer edge thereof to engage with an can he employed for this purpose.

overhead track 13 by means of trolley-Wheels M or. the like and passing through the air loe yond the ein?, land upon a sta e o r platform i5. The ydescent of the-vehic e to the platform 15 is provided for hy lowering the track i3 from the position shown in full lines to that shown in dotted lines. This is accomplished in any desired way--aafor enample iiy a supporting-har i6, directed hy stas tionary guides i7 and controlled hy a fall andtackle id or the hire. i have illustrated no particular means for operating trie fall and tackle, as it will he readily understood that any ordinary motive power or the like in Fig. ii is shown a construction in which a pair of tracks i3@ cnf a frame' i3@ support pair 'of trolley-wheels 14a, mounted on a shait Mb, connected with a hraolret 28%.' it wiil he noticed the traclr i3 is pivoter? at the point i9 to a stationary part of huilding or the like and that it is provided with-a leent portion 20, adapted to form, a near'iy hcrinontai track for the vehicle when it is lowered to the position shown in dotted lines. F'Vhenthe vehicle moves in the air, swinging from the trench: i3. to a position shown in the middle dotted position. scenery 2i, which can he seen hy the passengers in the vehicle, is given a downward motion, so to give the passengers the sensation of ascending, and after this position is passed the direction of motion of the scenery is reverse and its rapidity increased so to give yth impres sion of moving rapidly downward. o par ticular means for moving the sceneryisillustrated, as this feature is well known, and it can hel accomplished any of the known ways. xin order to provide for effeci'zualiy guiding the trolley-wheels onto the track i3, ii have provided a tapering guide iarge enough at the mouth to he sure to if 'ce the trolley-wheels into it and email en 3h at the end of the track 'i3 to force the Wheels to engage thetrach when they reach that point. This guide extends in a suhstantially horizontal direction to the right in order to provide a roof 23 at ,-a very short distance above the tops of the wheels M, so as to keep them from jumping thel tracli` while the roc' irc

'y inainvvheelsof the vehicle rest of the cli". To provide for guiding the vehicle to the. proper position on the platform 15, a pair of flaring guides 24 are arranged on the outside of this platform and converging towardy each other. Between these guldes are located a pair of rails 25. These also converge toward each other ata point 26 v and may,`,if desired, be used forgsupplying vWith a source of electrical energy and transmit power. through shoes 31, bearing u on them, and 'Wires 32 to a motor 33. It Wi l of course be understood that any system of running the motor may be employed, either electrical or mechanical, and that if an electrical means is used it can be either a-third rail, a

\ rangement.

battery system, or any other convenient ar- For a purpose to be described a battery 34 is located` in the vehicle or upon the frame and connected with the motor by means of Wires 35. A'llhe Wires 32 and 35 are preferably connected with a switch 36, located .in convenient yposition. for control by the operator in the vehicle. The motor is provided Witha gear 37 or other power-transmitting device, and this transmits motion to a gear or pinion 38, 'which is connected with a clutch member 39. 1'When thrown to the right, this clutch member engages its mate 46, and thus providesfor transmittingA rotation yto a pair of bevel-gears 41 which through a shaft 42, Wheels 43 and 44, and chain 45 transmit power to a shaft 46, which is the main shaft of the vehicle and on which the driving-Wheeis 47 are mounted. A brake 43 is conventionally represented upon the drivingshaftorder to control the operation of the driving mechanism, a lever 49 is connected with the clutch, and this by means of a link 56 is connected with a handlever 5i, pivoted to the vehicle and projecting into such a position as to be within the convement reach of the operator oi the vehicle.

- A spring 52 is empioyed for normally keeping the lever in central position, Where the clutch members 39 and 40 will not ,be in contact with each other, and a stop-segment 53, having'notches, is provided for holding the lever in two extreme positions on either side of the center. The pinion 33 and the clutch member 39 are slidingly mounted on a shaft 54, Which carries the ciu/tch member 40 and also another clutch member 55. A clutch mem ber 56, mating with the clutch member 55, is

upon the 'top propelling the vehi-` mounted rigidly With respect tothe pinion 38 and clutch member 39, and it Will be readily seen that When the lever 51 is swung to the position opposite that in which the clutch members 39 and 40 engage With each other the clutch members55 and 56 Will engage with eachother, thus transmitting motionv from ythe motor to a shaft 57, Which is rigidly mounted With respect to the clutch member 55. This shaft is provided with a crank 58, which passes through a pair of slots 59 in a pair of levers 60. These levers are mounted onv pivots 61, located upon the outer sides of the vehicle. Each of these levers is rigidly connected With a-pivoted frame 62, mounted It' will be seen on the outside of the vehicle. that the rotation ofthe shaft 5'7 Will cause the oscillation of these levers and also the oscillation ofthe frames 62 about their l ivots 61. Pivotally mounted upon each oft e frames 62 are a series of ribs 63. These ribs extend inward toward the body of thel vehicle and are provided With. elongated slots 64 near their inner ends. Abar65 is mounted longi tudinally with respect to the frame 62 and is provided with a series of pins or studs 66,

projecting through the slots 64. The two end ribs instead of beingprovided with slots are preferably provided with perforations of the same shape and size as the studs'66. It will be readily seen that the reciprocation of the bar 65 will cause the ribs 63 to oscillate upon the pivots' by which they are mounted upon the frame 62 and cause them to be spread into the position shown at the top in Fig. 1 in ICO dotted lines. Between the ribs there is prefj erably mounted a Web 67, consisting ofcloth or any desired kind of lexibie 'material This Web constitutes the body-of the Wing, and it Wiil be seen that when the ribs are spread,as indicated above, the appearance of a wing is given to the structure described. ln

,order to add to this eifect, the Wing is provided With a rear'Wardiy-extending rib 63,

which is mounted in a stationary position on I the body of the vehicie. it will be seen.' that i have thus provided for the spreading of thel Wing and aise for the vibra-tion or flapping of it. in order to v rovide for the reoiprocation ofthe bar 65 anthe consequent spreading of the Wing, a stud 69 is mounted, preferably,

near the front end of the bar, and a plate 76, i

hav-ing an eiongated slot 71 for receiving the stud, is mounted. on an arm 72 by means oi a pivoted connection. This arm 72v is connected With a slide 7 3 mounted in a guide 7 4 on the frame of the machine, and is rigidly connected bya bar 7 5 with a sliding frame 76, preferably located on the front part of the vehicle. it Will be apparent that the reciprocation of this frame 76 will cause the reci ,e rocation of the arm'72, and this motion Wi betransmitted through the stud to the bar 65 to spread the Wing. To provide for the reciprocation oi the frame 7 6, it is connected by a sie,

bration of lever. 51. Connected also Vwith the frame 76 area pair of links 82, pivotally connected together by means of a stud 83 or the like, and the end of oneof these links is pivotally connected with a bell-crank 84. This bell-crank is pivoted to aplate 85, which in turn is pivotally mounted, by meansv of a stud 86, on a stationary partI of the vehicle. From the bell-crank projects anA arm 87. Upon this arm are a pair of slides 88, connected. together by rods 89 and connected, by means of a link 90, with a projection 91 upon the plate 85.

This link 90 is pivoted both to the projection and to the'nearest slide 88.` Fixedly located upon theparm 87 at a point beyond each ofthe slides 88 is a .bracket 92. Pivotally connected witheach bracket is a link 93, and pivotally connected with each slide is a rib 94, to whichthe other end of one of the links 93is pivoted. It will be obvious that the sliding of the trame 76 in a rearward direction toward the frame oi the vehicle will cause the arm 87 to swing about the pivot on which the bell-crank 84 is mounted, which will cause these arms to rise from a horizontal `to an inclined or vertical position. It will also be seen that the same movement will cause. a reciprocation of the slides 88 with respect to the arm 87 and force the ribs to assume a position more nearly at right angles to the arm than that which they have previously occupied. This results inY the spreading of ythese front wings. It will be seenthat this operation is performed simultaneously with the spreadingof the side wings.

lin-order to provide for the oscillation of the front wings at the same time that the side winv s are' oscillated, a bell-crank 95, pivoted to t e frame ofthe vehicle, is connected with the frame 62 by a link 96. The bellcrank is also connected With the plate 85 by means of a link 97. It will be readily seen that the oscillation of the frame 62, caused A by the rotation of the shaft 57, will result in ofthe front wingsy could not a vibratory moqtion imparted to the plate 85, and consequently to the front wing. The

reason for pivoting the two links 82 together,

as Well as the reason for pivoting 'the two parts and 72 to each other, will be apparent when it is considered that'if these parts 'were rigidly mounted with respect to each other this oscillatory or fla ping movement be accomplished.

For guiding purposes the automobile is provided with a stationary axle 98, having extensions 99, on which the front wheels 100 are mounted. These extensions are pivoted with respect tothe stationary axle, being mounted on bellcranks 101. These two bell-cranks are connected together by a link 102. Means may be provided for operating the link so as to control the motion of the fronti wheels; but ordinarily this will not be desired on accountof the way in which l'prefer to uide the vehicle by the rails 25 and 27. T ese rails arepreferably located upon the inside of the wheels and eiiectually pre-- vent them from running in any course except that laid out by the rails.` They will alsov uide the wheels around curves and provide tor the leading of the vehicle vto the tracks after the leap is made in the manner indicated in Fig. 10. A rear wing or tail 103 may be provided for the vehicle, and it will be understood that this, as well as all the wings, will be provided with a Web similar to the web 67.

It will be understood that in case a thirdrail system is employed using the shoes 31 no power will be communicated to the motorafter the leap is commenced unless that 13a. As very little power will be required to oscillate the wings, it is desirablepfor a small battery 34 to be employed, and this can be connected with the motor as soon as the necessity for propelling the vehicle is removed. This battery is also connected, by means of wires 104, to a blower 105, although it will be understood that the blower can be operated in any other vdesired manner. is provided with a pair of discharge-pipes 106, which lead to upright pipes 107, running up the frame of the vehicle and provided with dlscharge-mouths 108, designed to ldirect a blast of air toward the assen ers in order to heighten the effect of ight t rough the air when the leap is being made.

In order to provide for further illusory effects in the way of simulating motion u or down an incline, the body of the vehicle is mounted upon a pivot 1-09 and is balanced by means of strong springs 110, so that norlmally it assumes a level position. A shaft 111- is mounted on the stationary part of the frame and connected by a link 112 with a bell crank 113, controlled by a lever 114 within easy reach of the operator. A segl ment 115 is provided with a notch 116 to f keep the lever in central position and assist the s rings 110 in keeping the body of the I vehic e level. When it is desired to give an l imitation of an` upward or downward motion, this lever is oscillated to the right or left, and

this will, through, the operation of the bell- This blower IIO ISO i o eration of the entire device. Supposing t e vehicle to be coming along the tracks 27 in the direction indicated in Fig. 7, the lever 51 will be moved from its forward position t'o that shown in full lines in Fig. 2. This will disconnect the clutch members 39 and 40, and conse uently disconnect the motor from the propel in mechanism. At this-time the wheels 14 wi lenter the guard 22 and be directed onto the rail 13, and as soon as the vehicle leaves the cliff 12 the operator will shift the lever 51 backward, so as to en age the clutch members 5.5 andy 56 and fat t e same timewill operate'the lever 80 to spread all the wings. This will cause themotor if at this time connected by means of the switch 36 with the battery to operate to flap the wings or oscillate'them about their ivots in the manner described.- above. At t e same timethe blower 105 can be connected by means of the same switch (which isl preferably a bi olar one) and cause air to be blown toward t e passengers. At the same time the scenery 21 is caused to descend and later to ascend, and all these operations tend to produce the. effect of flying through the air. The vehicle being suspended from above will be capable of having a swaying motion imparte to it, which will heighten this elect. As the car approaches the bent portion 2() of the track 13 it is preferably stopped and all of these scenic effects continued as long as may be desired. Then the fall and tackle 18 is operated to lower the track .13 about its pivot 19 to the lposition shown in dotted lines 1n Fig. 7, and t gravity onto the tracks 25. then intended to pass around a railway of any desired character throu h caverns and passages and past scenery suc as may be desired, and any desired means may of course beemployed to return it to a position from which 1t can again reach the cliff and track 27.

While I have illustrated and described onl one form in which my invention may be em odied, it will be understood that it is not limited thereto and that the principle ofthe invention may be'carried out in many ways.
